Unity 3.0 Font support

I know that it's currently not possible to modify the font leading of imported fonts in Unity 2.X. Is there information on Unity 3.0 font support that may allow this property to be set?

Unity will not let you set the leading on the font level (and Unity 3.0 won't allow that either). However, when using GUIText or TextMesh, it is possible to set the line spacing in the component. Unfortunately, I believe that there is no such option for using the GUI classes.
